Natural Hazards Research Summit 2022: Design for Tornadoes: How a Disaster and a Decade of R&D Led to the First-Ever Tornado Load Requirements in Building Codes and Standards

This poster gives an overview of how the devastating 2011 Joplin, MO tornado initiated a decade of R&D recently culminating in tornado load requirements being developed and adopted into the ASCE 7 Standard and the International Building Code. New science and engineering knowledge on tornado climatology, tornadic winds, and tornadic wind-structure interaction were used to create the first-ever engineering-derived probabilistic tornado wind speed maps that also account for the dependency of tornado risk on the plan size of the building.

本学术海报概述了2011年美国密苏里州乔普林市的毁灭性龙卷风如何开启了长达十年的研发工作，该研发近日迎来终局，促成龙卷风荷载要求被制定完成，并被纳入美国土木工程师学会（American Society of Civil Engineers, ASCE）7标准与《国际建筑规范》。研究团队依托龙卷风气候学、龙卷风流场以及龙卷风风-结构相互作用领域的前沿科学与工程学知识，打造出了有史以来首个由工程学推导得出的概率性龙卷风风速分布图，该分布图同时考量了龙卷风风险与建筑平面尺寸之间的相关性。
